What are the requirements for the ACP Randonneurs 10,000 award?
Complete at least 10,000 km of ACP brevets (NOT RUSA permanents) including a Paris-Brest-Paris, another 1200k, two full ACP series of 200, 300, 400, 600, and 1000 km brevets, a Flèche team event, and an ACP 600k brevet with at least 8000m
of climbing (or a Super Randonnée 600 before 10/31/2022)
within a six-year period [details
Basically, you have a choice. By October 31, 2022, finish a Super 600k, with its 10,000 meters of climbing and 60 hours allowed for completion, or after that date, your only option is to find and complete an ACP 600k brevet with 8000 meters of climbing and within 40 hours.
IMHO, It's much easier to finish a Super 600k with 10,000 meters in 60 hours, than finishing an ACP brevet with 8000 meters in 40 hours.
The clock is ticking if you wanted to use a Super 600k for your R-10,000.
